New one on me

[Greg Fretwell]

So that is not a split bus panel? My appologies.

[Speedy Petey]

In all my years I also always thought that was a split buss panel where both pull-out were "mains".

That's certainly what I'd call it.

[Speedy Petey]

So, if you pull the "Main" fuse block, does the range fuse block feed go dead?
I always thought no.

I've never actually tried this.

That's certainly what it is. The service splits into two directions (under two set of fuses) thus a "split" bus panel

Nope, the only thing that goes dead is the Edison or S-based fuseholders below and the subfeed lugs.

I THOUGHT SO. That diagram is "misleading" then.

I have to flip-flop then. I'm going back to 100A "split-buss".

That diagram certainly does show the range pullout powered from the load side of the 'main' fuses, but I've never seen one made like that. There might be some out there that way, but I can't recall running across one.

I know that I have looked at a few of those schematics for panels when I have inspected them, and that is the way I remember them being wired. I would say the best advice is to look for a label as to the panel rating and look for a diagram/schematic.

It would be nice to be able to pull the fuses out to check the amperage, but the only time I might do that is if the house were vacant.

Marc, Joe, anybody else,
Do you have 1 or 2 books you would recommend that show the different types of panels. Old and new With the correct way of wiring them.
Thanks
Mark

Ask Bill Addiss here, Licensed Electrician he sells many books and may have some suggestions.

I have many old catalogs, and if you search the net, Google panelboards and look for manufactures specs:

Wouldn't really recommend you pull the pull-outs from an old panel. Reason being, they do sometimes "pull apart", and you'll have the handle and face of the pullout in your hand, and the guts will be stuck in the panel. Or worse, part of the guts will be on the handle yet, and part will be stuck in the panel. Pull it out at your own risk. Replacements are very hard to come by, since they are quite manufacturer and model specific.

Hmmm, I don't. The sticker on the door of the panel would be the information you'd need. Probably older versions of HP Richter's "Practical Electrical Wiring" would have some stuff. Published by Park Press since the 30's.

Well said Marc I would also like to remind our newer Home Inspectors we do a visual Inspection.
I am a retired Electrician and I do not pull any thing like that apart.
Visual is as far as I go.
Any concerns in any equipment .
Recommend further evaluation by qualified person. ...CRA...

Here'a an old book that will be helpful for inspecting old wiring systems.
